Table 11-5 Agilent/HP 70420A Test Set Signal Input Limits and Characteristics
Limits
Frequency 50 kHz to 1.6 GHz (Std)
50 kHz to 26.5 GHz (Option 001)
50 kHz to 26.5 GHz (Option 201)
Maximum Signal Input Power Sum of the reference and signal input
power shall not exceed +23 dBm
At Attenuator Output, Operating Level
Range:
• RF Phase Detectors 0 to +23 dBm (Signal Input)
+15 to +23 dBm (Reference Input)
• Microwave Phase Detectors 0 to +5 dBm (Signal Input)
+7 to +10 dBm (Reference Input)
• Internal AM Detector 0 to +20 dBm
• Downconverters:
Agilent/HP 70422A 0 to +30 dBm
Agilent/HP 70427A +5 to +15 dBm
CAUTION:
To prevent damage to the Agilent/HP 70420A test set’s hardware components,
the input signal must not be applied to the test set’s signal input connector until
the input attenuator (Option 001) has been correctly set by the phase noise
software, which will occur at the connection diagram.
Characteristics:
Input Impedance 50 ohm Nominal
AM Noise dc coupled to 50 ohm load
